Two kinds of biliary duct obstruction after cholecystoduodenostomy. (A) The anatomic basis for a technical error that cost the life of 3 patients. Distal ligation of the double-barreled extrahepatic duct system resulted in total biliary obstruction. This recurrent accident has caused us to perform cholangiography on all liver homografts before transplantation. (B) The kind of biliary obstruction caused by stenosis of the cystic duct. Martineau reported that cytomegalovirus infection of the duct could be responsible for this development.

Schematic representation of the bacterial contamination or lack thereof in three different kinds of biliary reconstruction. (A) cholecystoduodenostomy. This extremely simple operation probably carries the greatest risk of graft infection. (B) Roux-en-Y cholecystojejunostomy. This operation protects from hepatic sepsis by placing the new liver outside the main gastrointestinal stream. The isoperistaltic limb is made at least 18 in. long. (C) Roux-en-Y choledochojejunostomy. The end-to-end duct-to-bowel anastomosis is simple if the duct is dilated, as would be the case if a conversion became necessary from B to C.

Post-transplantation cholangiographic studies. (A) Intravenous cholangiogram in a 47-year-old recipient of a hepatic homograft, the biliary drainage for which was with Roux-en-Y cholecystojejunostomy (). The patient’s liver function studies were normal at the time of the examination. However, the findings of a very slightly dilated common duct and air in the biliary system (arrows) are suspicious for low-grade obstruction. (B) A percutaneous transhepatic cholangiogram performed 4 weeks post-transplantation because of persistent elevations of the serum bilirubin (8–10 mg/100 ml). At the time of transplantation, biliary drainage had been established with a Roux-en-Y cholecystojejunostomy (). After obtaining this study, the patient was re-explored, the gallbladder removed, and the Roux limb anastomosed to the dilated common duct (large arrow), as shown in . The patient’s jaundice rapidly cleared, and he now has normal liver function 3 months post-transplantation. GB, gallbladder; CD, common bile duct; C, cystic duct.
